AN EVALUATION OF CHARACTERISTICS OF <i>CLOSTRIDIUM CHAUVOEI</i> WHICH POSSIBLY INDICATE A HIGHLY PROTECTIVE STRAIN

Abstract

Summary A highly protective strain of Clostridium chauvoei was compared and contrasted with a number of less protective strains and strain variants. This strain was found to produce uniformly smooth colonies and was highly toxic to mice and pathogenic to guinea‐pigs. It possessed an O antigen common to all the strains of Cl. chauvoei and an H antigen which in this study was shared only by the standard challenge strain. Apart from flagella type, no single characteristic sets this strain clearly apart from other less protective strains.
